similar to: LVM - how to change lv from linear to stripped? Is it possible?

Hi list, I'm building a NFS server on top of CentOS 8. It has 8 x 8 TB HDDs and 2 x 500GB SSDs. The spinning drives are in a RAID-6 array. They are 4K sector size. The SSDs are in RAID-1 array and with a 512bytes sector size. I want to use the SSDs as a cache using dm-cache. So here what I've done so far: /dev/sdb ==> SSD raid1 array /dev/sdd ==> spinning raid6 array I've

Joe, Agree with you on turning this around into something more positive. One aspect that would really help us decide on our next steps here is the actual number of deployments that will be affected by the removal of the gluster driver in Cinder. If you are running or aware of a deployment of OpenStack Cinder & Gluster, can you please respond on this thread or to me & Niels in private

I'm pulling my hair out trying to setup a mirrored logical volume. lvconvert tells me I don't have enough free space, even though I have hundreds of gigabytes free on both physical volumes. Command: lvconvert -m1 /dev/vg1/iscsi_deeds_data Insufficient suitable allocatable extents for logical volume : 10240 more required Any ideas? Thanks!, Gordon Here's the output from the

The Gluster Community would like to congratulate the OpenStack Foundation and developers on the Havana release. With performance-boosting enhancements for OpenStack Block Storage (Cinder), Compute (Nova) and Image Service (Glance), as well as a native template language for OpenStack Orchestration (Heat), the OpenStack Havana release points the way to continued momentum for the OpenStack community.

Hi, I'm trying to setup the provisioning of new OpenStack hypervisors with cinder volumes on them. The problem is that kickstart doesn't allow dashed in volume group names? I tried this: volgroup cinder-volumes --pesize=4096 pv.02 and this: volgroup cinder--volumes --pesize=4096 pv.02 but in both cases I end up with a volume group named "cindervolumes" on the system. Any

Hi folks, I'm having a issue in the standard NFS driver on OpenStack, that uses qemu-img and libvirt to create snapshots of volumes. It uses qemu-img in the Controller to manage the snapshots when the volume is not attached (offline) or calls the Compute (which calls libvirt) to manage snapshots if the volume is attached (online). When I try to create/delete snapshots from a snapshot chain.

I'm still running CentOS 5 with Xen. We recently replaced a virtual host system board with an Intel S1400FP4, so the host went from a 4 core Xeon with 32G RAM to a 6 core Xeon with 48G RAM, max 96G. The drives are SSD. I was recently asked to move an InterBase server from Windows 7 to Windows Server. The database is 30G. I'm speculating that if I put the database on a 35G

In some cases we have observed the time taken for a Cinder volume to attach to the conversion appliance can be longer than the current 60 seconds. Increase the timeout to 5 minutes.

Hi All. I am currently using OpenStack Juno on CentOS 7. The problem is that by default OpenStack's Cinder service creates logical volumes of "linear" type. I would like to have them stripped over all physical disks to get better write performance. Is there a way to tell LVM to create by default stripped volumes instead of linear ones? BR, Rafal.

Hello list, I've been having a tough time adding windows resource support to my ogg vorbise decoder, although I think I am close. Basically when I call ov_open_callbacks(), it doesn't ever return and repeatedly calls my seek_func. I'm hoping it is something obvious, but I can't see why my seek_func is being called endlessly. If the file is seekable, I should return 0, right? If

I am hoping I can get a little light she on a problem I am having trying to bring up a guest domain. I suspect that the problem is in my supplied file system First the environment. VT enabled dual core EM64T processor, Asus Mb (I can get the exact chipset infor if relevant) 2 Gig of DRAM SATA drives. I have build and booted the domain 0 using 3.0.2-2 version of xen. This seems ok.

I''m happy to announce the release of version 2.0 of the Puppet Labs OpenStack modules to the Puppet Forge. These modules handle the deployment and management of the latest Grizzly releases of OpenStack, including Keystone, Swift, Glance, Cinder, Nova, and Horizon. Additionally, an OpenStack module is provided for single or multi-node deployments. Here is a set of links to the Forge

Hi all, I'd like to get a few storage statistics from a running vm. I'd like to know read and write data about QCOW2 devices and about RBD volumes. I did try to execute a command similar to this: virsh qemu-monitor-command vm-vnc '{ "execute": "query-block"}' as described here:

This patch implements output to OpenStack Cinder volumes using OpenStack APIs. It has only been lightly tested, but appears to work. There are some important things to understand about how this works: (1) You must run virt-v2v in a conversion appliance running on top of OpenStack. And you must supply the name or UUID of this appliance to virt-v2v using the ‘-oo server-id=NAME|UUID’ parameter.

This patch series lifts the previous restriction that virt-v2v would refuse to convert a guest to Glance that had more than one disk. The first patch is just better documentation for the Glance output mode. The second patch contains the change (best viewed with 'git diff -w' since it is mostly a whitespace change). virt-v2v -o glance will now create multiple disks called: - guestname
